Do not forget also the Special One who is always crying and blaming ghosts for his repetitive defeats.
Unfortunately, some coaches are like this. They do not have mistakes, they are perfect but the weather is against them, the stadium is in bad shape, the referee is helping their opponents, VAR should be banned if it doesn't help them, players didn't follow their tactics, blame a random player for his catastrophic mistake, say the administration didn't accept to recruit highly expensive players who are needed for his strategy.
All these are a small collection of the excuses used by these coaches and you can find more and more everyday.
